Adult entertainer Natasha Stewart, who uses the name Pebbelz Da Model, is charged with depraved-heart murder and other counts in the death of 37-year-old Karima Gordon, of Atlanta.

Prosecutors said Gordon paid Stewart $200 for a referral to the suspected injector.

Authorities said Gordon died from blood clots in her lungs days after being injected with a silicone-type substance.

Hinds County Circuit Court Judge Bill Gowan said Friday that the defense may have to hire a new witness. He says he'll continue the trial if prosecutors need time to prepare arguments based on the expert's findings.
